Directional Spool Valve H-4WEH25G6X/6EG24N9K4/B10 - Bosch Rexroth R901316821
At 400 l/min instead of 700 l/min, size 25 keeps more margin against cavitation in the spool. This version with spool symbol G and B10 pilot works in that range, withstands 350 bar operating pressure and weighs 18.08 kg.

Description
The H-4WEH25G6X/6EG24N9K4/B10 directional spool valve directs up to 400 l/min in size 25 following spool symbol G. Permissible operating pressure is 350 bar, pilot oil is fed in and drained externally.
Benefits
- Flow up to 400 l/min at operating pressure up to 350 bar
- Spool symbol G, three switching positions, four ports
- B10 pilot version with external pilot oil supply and return
- Solenoid actuation at 24 VDC, 3-pole connector (2 + PE) to EN 175301-803
- ISO 4401-08-08-0-05 hole pattern, NBR seals, weight 18.08 kg
Application
The valve controls cylinders and hydraulic motors in medium-power units whose flow exceeds size 16. External pilot oil routing keeps the pilot stage independent of working pressure. Mounting is on a subplate to ISO 4401-08-08-0-05.
Manufacturer
Bosch Rexroth lists this valve under material number R901316821. Further data is given in the manufacturer datasheet.
